UVB-2 Bitumen modification unit 20 m3/hour production capacity

This is a 20 m3/hour bitumen modification1Polymer modification of bitumen is the incorporation of polymers in bitumen by mechanical mixing or chemical reaction. unit. The growing road construction and repair market leads to growing modified bitumen demand.

The 20 m3/hour unit solves that problem. The double stream process used in this unit reduces the load on the shearing part of the mill2A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. and extends mill service life.

The compatibility of bitumen and polymers is essential to obtain a high-quality final product. The polymer can absorb oil components of the binder, preserving its structure. Due to the modification process, bitumen is turned into an elastomer3An elastomer is a polymer with viscoelasticity (i.e., both viscosity and elasticity) and very weak intermolecular forces, and generally low Young’s modulus and high failure strain compared with other materials. with improved elasticity.

Modern petrochemical industry professionals attempt to maximize the yield of light oil products and extract most of the paraffin-naphthenic fractions from bitumen4A bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum.. This reduces its flexibility at low temperatures and softening point at high temperatures. Most modern bitumen will lose elasticity5Elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. at approximately twenty degrees (20 0C) and begin to soften between +45 0C and 48 0C. The use of non-modified bitumen in both road construction, which requires a binder with a temperature range from -40 0C to +70 0C, and for roofing materials6Roofing material is the outermost layer on the roof of a building, sometimes self-supporting, but generally supported by an underlying structure., which are often subjected to temperatures up to 90 0C, is inefficient. Fortunately, there are ways to change and improve the properties of bitumen by mixing it with various additives. This is best achieved using special bitumen modification units such as the GlobeCore UVB bitumen modification system.
